Abstract

Efficient field-effect mobilities measured from both p- and n-type organic monolayer field-effect transistors that utilize graphene electrodes permit quantitative analysis of the role of the first layer. Information about the relationship between the kinetics of the diffusion process and film morphology of the first layer during the increasing substrate temperature, and correlations of field-effect mobilities of the first monolayer and the substrate temperature is obtained.
